following error.

Tue Jun 21 20:04:31 2011 [TM][W]: Ignored: TRANSFER SUCCESS 211 -

When I check the cluster node for the /dev/dm-0, the device mapper for the
logical volume created during VM creation, it shows me that /dev/dm-0 is
present.

Hope someone could throw some light on this error.

Regards,
Prakhar
